Data suggests Assad, ISIS have been ignoring each other on the battlefield

Both sides in the bloody conflict appear to be eliminating smaller rivals ahead of a possible final showdown.

Around 64 percent of verifiable ISIS attacks in Syria this year targeted other non-state groups, an analysis of the IHS Jane’s Terrorism and Insurgency Center’s (JTIC) database showed. Just 13 percent of the militants’ attacks during the same period — the year through Nov. 21 — targeted Syrian security forces. That’s a stark contrast to the Sunni extremist group’s operations in Iraq, where more than half of ISIS attacks (54 percent) were aimed at security forces.

“In Iraq, it’s a very clear insurgency: them against the Iraqi state,” said Matthew Henman, head of JTIC. “In Syria, it’s a different situation because you have such a proliferation of competing, non-state armed groups in the country in addition to Assad.”
